Abstract

Abstract An image on the original to be printed on a print sheet (P in ) by a printing machine (13) is scanned by a scanner (20), and the data is edited by an editing section (10). The edited data is converted from the data dependent on the device (printing machine) to data not dependent on the device with the use of a device profile (P 1 ) included in a converter (11). A luminous-environment conversion circuit (12) compensates the data sent from the converter (11) according to the data corresponding to surrounding light, output from a sensor (S 1 ), and data related to the paper color of the print sheet (P in ), output from a sensor (S 2 ). Another luminous-environment conversion circuit (15) compensates input data according to the paper color of a print sheet (P out ) in a printer (30) or surrounding-light data, output from sensors (S 3 and S 4 ). Another converter (16) converts the output of the luminous-environment conversion circuit (15) to data dependent on the printer (30) and the data is printed on the print sheet (P out ) by the printer (30).

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 149 words
An image processing apparatus for matching the appearance of an image on a first hard copy to be output from a first image output apparatus to the appearance of an image on a second hard copy to be output from a second image output apparatus, comprising: first obtaining means for obtaining the color of the paper of the first hard copy and luminous-environment data; second obtaining means for obtaining the color of the paper of the second hard copy and luminous-environment data; first conversion means for converting the DDC data of the image to be output on the second hard copy into DIC data; compensation means for compensating the DIC data according to the luminous-environment data obtained by said first obtaining means and the luminous-environment data obtained by said second obtaining means; and second conversion means for converting the DIC data compensated by said compensation means to DDC data.
Claim 2
Dependent Claim 154 words
An image processing method for matching the appearance of an image on a first hard copy to be output from a first image output apparatus to the appearance of an image on a second hard copy to be output from a second image output apparatus, comprising: a first obtaining step for obtaining the color of the paper of the first hard copy and luminous-environment data; a second obtaining step for obtaining the color of the paper of the second hard copy and luminous-environment data; a first conversion step for converting the DDC data of the image to be output on the second hard copy into DIC data; a compensation step for compensating the DIC data according to the luminous-environment data obtained in said first obtaining step and the luminous-environment data obtained in said second obtaining step; and a second conversion step for converting the DIC data compensated in said compensation step to DDC data.
Claim 3
Dependent Claim 167 words
A transfer medium for transferring a computer program used for an image processing apparatus which matches the appearance of an image on a first hard copy to be output from a first image output apparatus to the appearance of an image on a second hard copy to be output from a second image output apparatus, said computer program comprising: a first obtaining step for obtaining the color of the paper of the first hard copy and luminous-environment data; a second obtaining step for obtaining the color of the paper of the second hard copy and luminous-environment data; a first conversion step for converting the DDC data of the image to be output on the second hard copy into DIC data; a compensation step for compensating the DIC data according to the luminous-environment data obtained in said first obtaining step and the luminous-environment data obtained in said second obtaining step; and a second conversion step for converting the DIC data compensated in said compensation step to DDC data.
